Hello dear,
In this post, you have not mentioned your gender.
First of all, please do not get influenced by any advertisement or health product which claim to boost your
growth hormone & increase height...it may be harmful.
Height of an individual is determined by Genetics, Environmental & Nutritional factors and
Hormonal factors (most important the Growth Hormone secreted by
pituitary gland in brain)
An individual stops growing in height after the fusion of the Epiphyses (growth plates) of the long bones, which occurs by the age of 16-18 yrs in females and 17-21 yrs in males.
So...as you are 24 yrs old now, the fusion of epiphyses might have taken place.
An
X ray for
bone age determination can be taken to look for the same.
Under such circumstances, enhancement in height can be possible only through surgical measures.
Kindly consult an Orthopedician & discuss regarding this.
Wishing you Good Health.
Take care.
